Fault tolerant model predictive control of three-phase permanent magnet synchronous motors [PDF]
, 2013 A new fault tolerant model predictive control (FTMPC) strategy is proposed for three-phase magnetically isotropic permanent magnet synchronous motor (PMSM) with complete loss of one phase (LOP) or loss of one leg (LOL) of the inverter.
